The last 12 hours I've been in "Tyranid color scheme Hell". This morning I must have tried six different things, each more hideous than the last. Then I hit paydirt. I think I got it. Or at least something I like.

Note this is a rough mockup, a practice sample, done at L3.

Don't have a name for them yet. Might keep Deepwater Nids as the nickname. I am quite relieved. Now I can get busy on the other models. Plus I'm glad the teal didn't work out since that would have followed the trend of other armies.
